Hello, downloaded updated driver for compatable memory card. Worked fine yesterday. Put PC in Standby mode and this morning Monitor will not wake up from "Standby". I did a manual shutdown and reboot, still no Display screen but assume computer is waiting at the signo n screen. How do I log on to PC using keyboard commands so that I can use keyboard commands to put comupter into Hibernation and see if Monitor will wake up from hibernation mode
